The extension o-ring comes from the factory clean an lightly
lubricate . It shoul not be necessary to remove the o-ring,
however we recommen applying a light coating of lubricant, just
enough to make if feel slick. Remove any excess lubricant as it can
collect foreign particles which can interfere with sealing.
If it becomes necessary to remove the o-ring from it’s groove, use a
non-sharp instrument such as a small flat bla e screw river. O-
rings can be cleane with fresh water. To lubricate the o-ring, put a
small amount of lubricant on your finger tips an raw the o-ring
through your fingers. Use only a
small amount of lubricant. When
rawing the o-ring through your
fingers o not stretch the o-ring.
On the insi e of the Extension
Ring just below the internal
threa s is a flat sealing surface.
This sealing surface is where the
o-ring on the Port Bo y will seal
when they are screwe together.
Make sure it is clean.

The Canon lens is smaller in iameter requiring the shorter Control
Spacer be installe between the port bo y an knob.
To install the optional Canon Control Spacer, use the supplie allen
wrench to loosen the knob allen screw. Remove the knob an
Nikon Control Spacer. Install the Canon Control Spacer, remount
the knob, an tighten the allen screw. Note there is a flat on the
control shaft against which the allen screw shoul tighten.

When using the #5510.75 Port Extension, both Canon lenses must
be use with the #5510.16 port bo y only, otherwise the Focus
Extension Control will not line up properly in relation to the lens
focus ring. The Nikon VR lens will align properly when use with
either port bo y #5510.16 or #5510.22.
